Earth’s 10 billion atomic bomb-blast: when an asteroid killed our planet (science news).

when the asteroid that called time on the dinosaurs smashed into the Earth, the impact set wildfires, triggered tsunamis and blasted so much sulphur into the atmosphere that it blocked the sun, which caused the global cooling that ultimately doomed the dinosaurs. That’s the scenario scientists have hypothesised. Now, a new study led by The […]

NASA’s asteroid bounty bounce (science news).

After months grappling with the rugged reality of asteroid Bennu’s surface, the team leading NASA’s first asteroid sample return mission has selected four potential sites for the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to “tag” its cosmic dance partner. Since its arrival in December 2018, the OSIRIS-REx spacecraft has mapped the entire […]

Apophis, the Earth-killer asteroid gets people scared.

On April 13th 2029, a scratch of light will streak across the sky getting brighter and faster. At one point it will travel more than the width of the full Moon within a minute and it will get as bright as the stars in the Little Dipper. But it won’t be a satellite or an […]

Bering Sea meteor strike last Christmas could have destroyed New York and killed 20 million.

Last December (2018), an untracked and rather unexpected meteor exploded over the Bering Sea releasing 173 kilotons of energy, or more than ten times the energy of the Hiroshima atomic bomb blast. To put this event in context, if this meteor came in on a less fortunate angle and hadn’t air-burst, but instead struck the […]

NASA’s newly landed OSIRIS-REx probe discovers water on asteroid.

Recently analysed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Bennu. During the mission’s approach phase, between mid-August and early December, the spacecraft travelled 1.4 million miles (2.2 million km) on its journey from Earth to […]

OSIRIS-REx spacecraft says hello to Asteroid Bennu.

NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft completed its 1.2 billion-mile (2 billion-kilometer) journey to arrive at the asteroid Bennu Monday. The spacecraft executed a maneuver that transitioned it from flying toward Bennu to operating around the asteroid. Now, at about 11.8 miles (19 kilometers) from Bennu’s Sun-facing surface, OSIRIS-REx will begin […]

Help save humanity from asteroid extinction with a single download.

A software application based on an algorithm created by a NASA challenge has the potential to increase the number of new asteroid discoveries by amateur astronomers. Analysis of images taken of our solar system’s main belt asteroids between Mars and Jupiter using the algorithm showed a 15 percent increase in positive identification of new asteroids. […]

Catch me an asteroid!

NASA’s first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016. The Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) passed a confirmation review Wednesday called Key Decision Point (KDP)-C. NASA officials reviewed a series of detailed project assessments and authorized the spacecraft’s continuation into […]
